# Prestructured Queries

Using a patient's unique Assembled graph instance as input for Synthesize enables developers to preset queries to run automatically any time data in the record is updated. 

## **Concordance**

The first of these endpoints is `/concordance` which automatically surfaces and synthesizes the guidelines for each of the problems on a patient's problem list. Responses are contextualized to the data in a patient's record corresponding not just to their current care plans, but their medical history, including labs, pre-existing conditions, and risk factors. 

### Endpoint

```
POST /v1/concordance
```

### Authentication

All requests require an API key passed in the request header:

```
x-api-key: <your-api-key>
```
